Antenna assemblies including antenna elements with dielectric for forming closed bow tie shapes

摘要

According to various aspects, exemplary embodiments are provided of bow tie antennas and antenna assemblies that include the same. In an exemplary embodiment, a bow tie antenna includes a pair of antenna elements. Each antenna element includes spaced apart end portions defining an open portion such that the antenna element has an open shape. The open shape is closed by dielectric material disposed between the spaced apart end portions and extending across a gap separating the spaced apart end portions, whereby the dielectric material and pair of antenna elements cooperatively define a closed bow tie shape for the bow tie antenna.

主权项

1. An antenna assembly operable for receiving digital television signals, the antenna assembly comprising:
an antenna support; at least one bow tie antenna coupled to the antenna support; and at least one reflector coupled to the antenna support and disposed relative to the at least one bow tie antenna for reflecting electromagnetic waves generally towards the at least one bow tie antenna; wherein the at least one bow tie antenna comprises at least one pair of bow tie antennas spaced apart from each other; wherein the antenna assembly further comprises a balun and one or more pairs of electrical conductors electrically connecting the balun and the bow tie antennas; and wherein:
the balun is electrically equidistant from the bow tie antennas such that the bow tie antennas are in phase; and/orthe one or more pairs of electrical conductors form a parallel wire transmission structure; wherein the at least one bow tie antenna comprises a first pair of bow tie antennas coupled to the antenna support and spaced apart from each other, and a second pair of bow tie antennas coupled to the antenna support and spaced apart from each other, and wherein the antenna assembly further comprises:
a first reflector behind the first pair of bow tie antennas for reflecting electromagnetic waves generally towards the first pair of bow tie antennas; anda second reflector behind the second pair of bow tie antennas for reflecting electromagnetic waves generally towards the second pair of bow tie antennas.
